Question: Are Height And Weight Continuous Variables?

What is discrete data example?

Discrete data is information that we collect that can be counted and that only has a certain number of values.

Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit..

What is an example of continuous random variable?

In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables. … Between any two values of a continuous random variable, there are an infinite number of other valid values.

Is height a continuous variable?

A variable is said to be continuous if it can assume an infinite number of real values. Examples of a continuous variable are distance, age and temperature. … For example, the height of a student is a continuous variable because a student may be 1.6321748755…

Is weight a continuous variable?

Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable. Foot length is also a continuous random variable. Continuous random variables are often measurements, such as weight or length.

Is height a continuous or discrete variable?

In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables.

Is family size a continuous variable?

The continuous variables can take any value between two numbers. … when family size is measured as a continuous variable. Household size and number of computers are discrete variables. The range is an important descriptive statistic for a continuous variable, but it is based only on two values in the data set.

What is meant by continuous variable?

Continuous variables can take on an unlimited number of values between the lowest and highest points of measurement. Continuous variables include such things as speed and distance. … Discrete data are associated with a limited number of possible values.

Is a grade discrete or continuous?

For example, the grade you receive in your school exam (A, B, C, D, or E) is an example of discrete data because your grade can only take on one of these 5 possible values and nothing else. Discrete data can be further sub-divided into three categories: binary, nominal and ordinal.

Is grade a continuous variable?

Ordinal (ordered) variables, e.g., grade levels, income levels, school grades. … Continuous variables grouped into small number of categories, e.g., income grouped into subsets, blood pressure levels (normal, high-normal etc)

Is Money discrete or continuous?

A continuous distribution should have an infinite number of values between $0.00 and $0.01. Money does not have this property – there is always an indivisible unit of smallest currency. And as such, money is a discrete quantity.

What are the types of continuous variables?

There are two types of continuous variables namely interval and ratio variables.Instant variable.Ratio variable.Oct 12, 2020

Is percentage grade continuous or discrete?

In practice, percentage data are often treated as continuous because the percentage can take on any value along the continuum from zero to 100%. In addition, dividing a percentage point into two or more parts still makes sense. Discrete data are easy to collect and interpret.

Is height and weight discrete or continuous?

Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.

What are two examples of continuous variables?

You often measure a continuous variable on a scale. For example, when you measure height, weight, and temperature, you have continuous data. With continuous variables, you can calculate and assess the mean, median, standard deviation, or variance.

Is gender a continuous variable?

Gender can be a continuous variable, not just a categorical one: Comment on Hyde, Bigler, Joel, Tate, and van Anders (2019)

Is age group a continuous variable?

There are 2 types of numerical variables: ● Continuous variable: A numerical variable that can take values on a continuous scale (e.g. age, weight). … ○ Ordinal variable: A categorical variable where the categories have a natural ordering (e.g. age group, income level, educational status).

What is the difference between a discrete and continuous variable?

A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. … A discrete random variable X has a countable number of possible values.

Is age continuous or discrete?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.
